    [0001] FIELD OF THE INVENTION The present invention relates to the field of three-wheeled land vehicles and more particularly to the conversion of two-wheeled vehicles into three-wheeled vehicles. BACKGROUND OF THE INVENTION Tricycles are three-wheeled vehicles with human or mechanical propulsion, streamlined or not. They have particular advantages over two-wheeled vehicles in terms of stability and payload. Tricycles are used, among other things, for the transport of loads or people in urban areas, or by people with balance difficulties such as children, the elderly or the motor deficient. Conventionally, a tricycle comprises a carrying frame comprising a steering front fork receiving a front wheel and a propulsion rear axle carrying two rear wheels rotatably connected to a shaft driven by a chain or belt driven by an engine or by the muscular force of the user. Tricycles are, despite their advantages, very little disseminated to cycle dealers, particularly because of the low sales volumes and the large size of these vehicles in the stocks. This situation makes the delivery times of a tricycle are long because they are usually made on demand. There are tricycle bicycle conversion kits that include a rear axle and a drive gear of a shaft connecting the two rear wheels carried by the axle. These kits are usually provided with a specific frame portion to replace all or part of the rear fork of the bicycle. The user is then obliged to deposit all or part of the rear fork and report, usually by welding, the specific frame portion. This conversion is irreversible and requires special skills and equipment. Finally, such a device requires a differential that further increases the cost and complexity of the conversion kit. There is therefore a need for a reversible conversion solution of a two-wheeled vehicle into three-wheeled vehicles, which can be implemented in a simple manner. OBJECT OF THE INVENTION An object of the invention is to allow a simple conversion of a two-wheeled vehicle into a three-wheeled vehicle.
    [0002] SUMMARY OF THE INVENTION For this purpose, provision is made, according to the invention, for a device for converting a two-wheeled vehicle into a three-wheeled vehicle, the two-wheeled vehicle being provided with a frame comprising a fork provided with means for accommodating a hub of a wheel, the conversion device comprising: a steering support frame connected to an axle provided with two flare bearings accommodating respectively a rotation of a steering knuckle of a first and a a second wheel; - Two rods whose first ends are respectively integral with the steering knuckles of the first wheel and the second wheel, and whose respective second ends are hinged to a steering rod mounted to rotate on the steering support frame; a steering column whose first end is integral in rotation with the steering rod; the steering column comprising means for its connection in rotation with the front fork and the steering support frame, the connecting means comprising a connecting arm with the frame of the vehicle.

The first end of a rectangular eccentric plate 20 is articulated on a first end 21 of the lever 14.3 by means of a locking hinge 22. The second end of the eccentric plate 20 is connected by a ball joint to the first end 23 of a connecting rod 24.
    [0004] In a symmetrical manner with respect to the longitudinal plane Pv, the rocket 15 comprises a first part 15.1 engaged in the bearing 13, a hub 15.2 and an orientation lever 15.3, a first end 25 of which is connected by a ball joint to the first end 26d. 27. The hubs 14.2 and 15.2 are arranged to provide a defined camber to the wheels 18 and 19 mounted thereon. Rockets 14 and 15 also carry brake calipers which have not been shown for reasons of clarity. The respective second ends 28 and 29 of the rods 24 and 27 are provided with ball joints cooperating with two vertical axes 30 and 31 of a first end 32 of a steering rod 33 rotatably mounted along an axis 34 on a shaped upright 35. L of lower projecting from the middle of the crossbar 4. A steering column 36 comprises a first cylindrical tubular portion 37 provided with a first yoke 38 rotatably receiving a second yoke 39 about an axis of rotation 40. The yoke 39 is itself hinged to the connecting rod 33 along an axis 41 perpendicular to the axis 40. As can be seen in FIG. 4, the articulation of the axis 41 of the yoke 39 on the connecting rod 33 is in line with the articulation axis 34 of the rod 33 on the upright 35 and secant with said axis.
    [0005] The inclination of the arms 8 and 9 with respect to the steering support frame 2, the camber of the wheels 18 and 19 as well as the length and the implantation of the upright 35 lead to a position of the axis of rotation 41 located under an axis. horizontal connecting two homologous points of the hubs 14.2 and 15.2 on which are mounted the front wheels 18 and 19, such as, for example, the points of intersection of the axes of rotation of the first parts 14.1 and 15.1 of the steering knuckles 14 and 15 with the the axis of rotation of the hubs 14.2 and 15.2 of the wheels 18 and 19. According to a preferred embodiment, the axis 34 of rotation of the steering rod 33 is inclined in a vertical plane at an angle y of 75 degrees to in a horizontal direction H. The axis 41 is inclined in a vertical plane at an angle of 30 degrees to a horizontal direction H. The first portion 37 of the steering column 36 is bonded by welding at the a junction interface 42 to a second tubular portion 43 of square section whose end 44 opposite the junction interface 42 comprises a slot 45 extending along the axis of the steering column 36. This light 45 receives a bolt 46 on the screw which is engaged a substantially rectangular bar 47 extending perpendicularly to the axis of the steering column 36. The bar 47 comprises two bores 48 and 49 at each of its ends 47.1 and 47.2. A shaft 50 secured to the steering column 43 extends in a direction perpendicular to the axis thereof at the junction interface 42. The shaft 50 has a cylindrical stud 51 at each of its ends. The conversion device 1 also comprises a connecting arm 52 rigidly connected at its first end 53 in the middle of the crossmember 3 of the steering support frame 2. The second end 52.1 of the connecting arm 52 comprises a sleeve 54 in which a tree slides 56 at the end of which is screwed a ball 55. The relative position of the ball 55 and the shaft 56 is adjustable by screwing or unscrewing the ball 55. The ball 55 receives an elastomeric pad 57 secured to a screw 58 A helical spring 59 is supported at a first end on the end 52.1 of the sheath 52 and in one second of its ends on a shouldered end of the shaft 56, allowing damping of the relative movement of these two elements. The conversion device 1 also comprises a stop device 60 (clearly visible in FIG. 2) pivotally received in a bearing 61 around a horizontal axis perpendicular to the longitudinal plane Pv. The bearing 61 is located in the middle of the cross member 3 of the steering support frame 2. The stop device 60 comprises two fingers 62 and 63 located on either side of the bearing 61. The stop device 60 can take two positions: a first parking position, represented in FIG. 2, in which the fingers 62 and 63 enclose the first cylindrical portion 37 of the steering column 36 and a second so-called use position shown in FIG. 1 and 3 which is obtained by approximately 180 ° rotation of the fingers 62 and 63 in the bearing 61. In the first parking position, the rotation of the steering column 36 about the axis 40 is blocked by the fingers 62 and 63. In the second position of use, the rotation of the steering column 36 about the axis 40 is allowed. It is however limited between two extreme positions defined by the longitudinal members 5 and 6 of the support frame 2. The passage of the stop device 60 from one position to the other can be done by direct manipulation but also with the aid of any remote control device such as a cable, electrical, pneumatic or hydraulic device. The conversion device 1 will now be described in application to the conversion of a two-wheeled vehicle, here a bicycle 70, into a three-wheeled vehicle. Referring to Figure 6, the bicycle 70 is provided with a tubular frame 71 comprising a steering front fork 72 rotatably mounted about an axis 73 of a tube 74 of a median portion 75 of the frame 70. The fork front 72 comprises two axes 72.1 and 72.2 brake supports around which pivoted brake shoes not shown. The front fork 72 also comprises, at its distal ends, two eyelets 72.3 and 72.4 for receiving the hub of a front wheel, not shown. The middle portion 75 comprises a seat post sheath 76 extending in a substantially vertical direction in the representation of Figure 6. The lower end of the seat post 76 is integral with a bearing 77 of horizontal axis receiving a pedal not shown. Two lower tubes 78 and 79 extend on either side of a vertical plane of a rear wheel 80 in a substantially horizontal direction from the bearing 77 to join two tubes 81 and 82 integral with the seat post sheath 76 The junctions of the tubes 78 and 82 on the one hand and 79 and 81 on the other hand form the two respective attachment points of a hub 83 of the rear wheel 80. This hub 83 comprises means for driving the rear wheel 80 from the bearing 77, these means have not been shown for reasons of clarity, but they may be in the form of a belt or a chain. The lower tubes 78 and 79 are also connected to each other by a spacer 84 (visible in FIGS. 7, 8 and 11) of trapezoidal shape located near the junction of the tubes 78 and 79 with the bearing 77. This spacer 84 includes a bore 85 generally intended to accommodate a point of attachment of a parking stand articulated. FIG. 7 shows the conversion device 1 mounted on the frame 71 of the bicycle 70. The steering column 36 is fixed to the front fork 72, after removal of the front wheel, by engagement of the cylindrical nipples 51 and 52 in the eyelets 72.4 and 72.3. The position of the bar 47 is adjusted by sliding the bolt 46 into the slot 45 so that the shafts 72.1 and 72.2 are respectively engaged in the holes 48 and 49. The bolt 46 is then tightened. The relative position of the ball 55 in the shaft 56 is adjusted so that the screw 58 engages in the bore 85 of the spacer 84. A nut engaged on the screw 58 tightens the elastomer pad 57 on the spacer 84 and secures the link arm 52 to the frame 71. A three-wheeled vehicle resulting from the conversion of a bicycle 70 is thus obtained by means of a conversion device 1. The steering column 36 is linked in rotation at the fork 72 of the bicycle 70 via the pins 51 engaged in the eyelets 72.3 and 72.4 of the front fork 72 and by the bar 47, the holes 48 and 49 cooperate with the axes 72.1 and 72.2. The connecting arm 52 reduces the bending forces to which the fork 72 is subjected and thus allows the conversion of any type of bicycle, including racing bicycles whose fork is particularly thin. The connecting arm 52 also makes it possible to secure the behavior of the tricycle obtained thanks to the conversion device 1 in the event of blockage or abrupt increase or decrease in adhesion on one of the wheels 18 or 19 (for example when one of the wheels leaves a paved roadway and rolls in grass, or that it passes on a plate of ice). Indeed, in the case of a tricycle with two front wheels, a blockage or impact on one of the front wheels generates a torque on the entire front fork which is transmitted to the handlebars of the tricycle and tends to violently tear off the this from the driver's hands. On the contrary, the connecting arm 52 of the device of the invention prohibiting rotation of the steering support frame 2 in case of shock or blockage, the driver keeps control of the tricycle. The return from the three-wheeled vehicle to the original two-wheeled vehicle is done by depositing the conversion device 1 by unscrewing the screw 58, the bolt 46 and disengaging the pins 51 eyelets 72.3 and 72.4. The two positions that can be adopted by the stop device 60 have the following effects. In the first parking position, the fingers 62 and 63 constrain the movement of the steering column 36 about the axis 41 but allow the rotation of the steering column 36 about the axes 34 and 40. The frame 71 then remains in a substantially vertical position This position makes it possible to park the tricycle obtained thanks to the conversion device 1 without it collapsing under the effect of gravity by a rotation of the steering column about the axis 40. This first This position can also be useful at low speeds, for example during start-up phases or during pre-stop phases in which the speed of the tricycle is low. In the second position of use, the steering column 36 is free to pivot about the axis 41 between two extreme positions defined by the abutment of the portion 37 of the steering column 36 on the longitudinal members 5 and 6 of the steering support frame 2. FIG. 8 shows a situation in which the portion 37 of the steering column 36 abuts the spar 6 of the steering support frame 2 without any rotation of the steering column 36 about the axis 34. In this situation, it will be noted that the wheels 18 and 19 have made a rotation tending to rotate the tricycle on the same side as the one facing the frame 70 secured to the steering column 36 of the conversion device 1. inventor found that the improvement of the level of steering of the front wheels has originated in particular orientations of the axes of rotation 34 and 41 compared to a standard gimbal in which the angle would be 71 degrees és and the angle 5 would be equal to 0 degrees, corresponding to a horizontal axis 41. The amplitude of the rotation of the front wheels 18 and 19 is also improved thanks to the authorized amplitude of inclination of the frame 70 about the axis 41 authorized by the conversion device 1. The position of the axis of rotation 41 below an axis connecting two homologous points of the hubs 14.2 and 15.2 on which the wheels 18 and 19 are mounted increases the offset of the center of gravity of the driver-tricycle assembly for a given angle of inclination of the frame 71 relative to vertically. This results in a tricycle behavior obtained using the conversion device 1 extremely close to that of a two-wheeled vehicle in which it is sufficient to bend to initiate a turn. This behavior allows curve speeds higher than those allowed with known tricycles and a reduced adaptation time to the tricycle obtained using the conversion device 1.
    [0006] With reference to FIGS. 1 and 9 to 11, another particular characteristic of the conversion device 1 according to the invention will be detailed. As can be seen in FIG. 1, the lockable joints 10 and 11 respectively comprise a hinge pin 10.1 and 11.1 as well as a locking pin 10.2 and 11.2. Referring to Figure 9, the locking pins 10.2 and 11.2 each comprise a central axis 90 which is secured to a half-cylindrical portion 91 and a first end comprises a handling paddle 92 and the second end comprises a nipple Rotating guide 93. The locking pins 10.2 and 11.2 respectively block the joints 10 and 11 in an operating position shown in FIG. 1 by bringing their portion 91 into contact with plates 4.3 and 4.4 integral respectively with the ends 4.1 and 4.2. of the spar 4, as shown in Figures 9a and 9b. When a user wishes to unlock the releasable joints 10 and 11, he grasps the pallets 92 of the locking pins 10.2 and 11.2 and rotates 180 ° thereof. The half-cylinder-shaped portions 91 move away from the plates 4.3 and 4.4 and the arms 8 and 9 are unlocked and can be moved around their respective hinge axes 10.1 and 11.1, as can be seen in FIGS. 9c and 9d. The steering lever 14.3 comprises, at its second end 100 opposite the first end 21, a locking eyelet 101 of oblong shape and extending in a substantially vertical plane. Symmetrically with respect to the longitudinal plane Pv, the steering lever 15.3 comprises, at its second end 102 opposite the first end 25, a locking eyelet 103 identical to the eyelet 101. The steering support frame 2 comprises, as to it, two identical locking devices 104 and 105 located at the ends of the spar 3, and respectively facing the wheels 18 and 19. The locking device 104 comprises a locking pin 106 rotatably mounted about a horizontal axis in a bearing integral with the spar 3. The first end 107 of the locking pin 106 facing the wheel 18 comprises a flat portion 108 adapted to cooperate with the oblong eyelet 101. The second end 109 of the locking pin 106 comprises a manipulation lever 110 for orienting the flat so that its largest dimension is oriented horizontally or vertically. The locking device 105 similarly comprises a locking pin 111 comprising a flat surface 112 facing the wheel 19 and a lever 113 for handling. When it wishes to pass the conversion device 1 from an operating position to a storage position shown in Figures 10 and 11, the user unlocks the joints 10 and 11 by acting on the locking pins 10.2 and 11.2. It then unlocks the lockable hinge 22 linking the first end of the eccentric plate 20 to the first end of the lever 14.3. The relative rotations of the rod 24 and the eccentric plate 21 relative to the lever 14.3 then allow the rotation of the arm 8 about the hinge axis 10.1 as shown in Figure 11. The user can then fold the arms 8 and 9 in the direction of the connecting arm 52, to a storage position shown in Figures 10 and 11. In this position, the flats 108 and 112 of the locking devices 104 and 105 respectively face the locking eyelets 101 and 103 and can be engaged. The user then makes a rotation of 900 to the axes 106 and 111 to lock the link arms in the storage position. The hinge pins 10.1 and 11.1 extend in directions determined so that the camber of the wheels 18 and 19 is zero when the conversion device 1 is in the storage position.
    [0007] The conversion device 1 can therefore be easily moved into a storage position whether or not it is mounted on the bicycle 70. According to the variant embodiment shown in FIG. 12, the conversion device 1 comprises a tubular load support 110 reported by bolting on the crossbar 4 of the steering support frame 2. This load support 120 has the shape of a devil whose lower platform 121 is foldable on the uprights 122. Thus, the conversion device 1 allows to use a vehicle to two wheels for the transport of loads enjoying the advantages of the stability of a three-wheeled vehicle. The load support 110 therefore extends between the front wheels and is arranged so as not to hinder their movements. In particular, the load support 110 has a width smaller than the spacing of the front wheels when the conversion device is in its storage position.
    [0008] Of course, the invention is not limited to the embodiments described but encompasses any variant within the scope of the invention as defined by the claims.
